JOHN WILSON BROWN, .13., OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE ENTERPRISE MANUFACTURING COMPANY OF PENNSYLVANIA, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

ATOMIZER.

Original application filed May 4, 1910, Serial No. 559,291.

1912. Serial No. 705,822.

To all whom it may concern:

Be it known that I, JOHN WV. BROWN, Jr., a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Atomizers, (being a division of application filed May 1th, 1910, under Serial No. 559,291,) of which the following is a specification.

One object of my invention is to improve the construction of atomizers, whereby the flow of water to the point where the jet of air projects the water will be regulated automatically by the amount of water taken up by the jet of air.

A further object of the invention is to provide means for automatically regulating the height of the water in the reservoir of the atomizer.

In the accompanying drawings :-Figure 1, is a side view of a sand tempering and moistening apparatus, showing my improved atomizer; Fig. 2, is a front View of the atomizer; Fig. 3, is an end View; Fig. 4, is a sectional perspective view; and Fig. 5, is a view of one of the bearings which support the atomizer.

Referring in the first instance to Fig. 1, 1 is a frame having deflecting plates 2.

3 is the atomizer.

4 is the hopper and at the base of this hopper is a pair of crushing rolls 5 and 6, which break up the lumps of sand, so that the sand will flow in a finely divided state in front of the atomizer, which sprays sulficient water on the same to properly moisten it. The sand then falls onto the conveyor where it is carried away from the machine. If there is no sand passing in front of the atomizer, then the spray is projected beyond the lower deflecting plates and carried away from the apparatus.

The particular type of apparatus shown in Fig. 1, is fully set forth and claimed in an application for patent filed by me on the 1th day of May 1910, under Serial No. 559,291, of which this is a division."

The atomizer 3 consists of a trough 7, having a hinged cover 8, and the front edge 9 of this trough is lower than the back edge, as clearly shown in Fig. 4:, and along the front edge of the trough is a series of ribs 10 and these ribs extend over the edge and into the trough, as indicated at 11, Fig. 5. The

Specification of Letters Patent.

Patented Jan. 28, 1913.

Divided and this application filed June 25,

lower ends of the ribs terminate in a point 12. 13 is an inlet pipe and let is an air pipe having a series of nozzles 15, which terminate below the point 12 of the ribs. After the edges of the ribs are moistened and the air under pressure is projected in close proximity to the lower edge of the ribs, water is drawn through the trough over the face of the ribs by capillary attraction. Consequently, there is a thin film of water traveling on each edge of the ribs from the trough to the point 12, where it drops off into the path of the jet of air. The air breaks up this drop and projects it in a fine spray against a thin sheet of falling sand, moistening the particles sufliciently to give them the proper temperature.

The atomizer is mounted in suitable bearings 16, secured to the bars 17 forming part of the frame of the apparatus.

In order to keep the water in the trough always at the same level, I provide a vertically adjustable reservoir 18, which is connected to the trough through a flexible pipe 19, provided with a valve 20, and this reservoir is mounted on a screw 21 adapted to a nut 22 mounted upon bearings 23 on the frame of the apparatus, so that it can be adjusted vertically to regulate the height of water in the trough.

2 1 is a water supply pipe, which has a nozzle 25 directly above the reservoir and is provided with a valve 26.

27 is an overflow pipe from the reservoir which discharges into a waste pipe 28. By vertically adjusting the reservoir, so that the overflow will be in a line with the edge of the trough, an even discharge of water from the trough is assured.

I claim 1. The combination in a tempering or moistening apparatus, of an atomizer consisting of a trough having a series of external ribs projecting over one edge of the trough and into the trough, each rib terminating at the lower end in a point; and a pipe having a series of nozzles in line with the points of the ribs, so that, when the fluid under pressure is projected from said nozzle, it will carry with it water passing from the trough over the ribs.

2. The combination in an atomizer, of a trough having a series of external ribs extending over one edge and into the trough and each terminating in a point at the lower end; and a series of spray nozzles located in close proximity to said points.

5 3. The combination of an atomizer consisting of a trough having a series of external ribs extending over one edge and into the trough and terminating in a point at the lower end; an air pipe having a series of 10 nozzles directly under the lower points of the ribs; a reservoir connected to the trough;

and means for Vertically adjusting the reservoir so as to regulate the flow of water to the trough.

In testimony whereof, I have signed my 15 name to this specification, in the presence of two subscribing witnesses.
